I typed my parent's e-mail address wrongly
Some students can correct it themselves, up to two times, before the parent has replied.
If you are in 100 level or JUPEB, you can correct a parent's or guardian's e-mail address yourself, up to two times, as long as that person has not yet replied. Open the parent e-mail correction page; the new address gets a fresh link.
Anyone else, or after the parent has replied, or for a phone number: ask the team, saying which parent and the correct details.
